  9. Weather at the South Pole • Data are binned by week. • Large dots show median • Thick bar shows 25%75% • Thin bar shows 10% 90% • Small dots show maximum and minimum measured values • Top panel shows PWV as measured by AIR Model 4a balloon flights 1991 to 1996 • Bottom 3 panels summarize hourly NOAA weather data from 1977 to 2001 Week of Year

  10. Climate • Temperature: • Average annual: -56.9 F • Record high: +7.5 F (December 1978) • Record low: -117.0 F (June 1982) • Average wind: 12.4 mph • Average pressure: 681.4 millibars • Average pressure altitude: 10,576 feet
